Abstract
Fracture toughness values of phenolphthalein poly(ether ketone) (PEK-C ) at 190 degrees C were determined by two different methods, i. e. the conventional crack growth method and the crack stress whitening zone method, which show consistent results. This indicates that the crack s tress whitening zone method can be used to determine the crack initiat ion of some polymers for which the blunting line concept is unsuitable .
